Common audio/video errors and solutions

Given below are some audio and video errors that occur in Chrome and Firefox browsers and solutions that will help you overcome them during online meetings and webinars.

Track start error or Not Readable error

This error occurs if audio and video are disabled in your Windows device manager. On Mac OS, it occurs if another Firefox tab is using your audio and video devices. It may also occur due to hardware errors at the OS, browser, and web page levels.
These errors may also occur due to OS level permissions in Mac OS Mojave. Please refer to the related section on this page.
  1. Close the application that uses the camera and/or microphone and refresh to allow access.
  2. Use a different microphone and camera.
  3. Switch to phone audio.

Camera not working in the latest chrome browser

Google flags are experimental features that Chrome is testing internally. Media Foundation Video Capture is one of them. Reportedly, enabling Media Foundation Video Capture on browsers might hamper the webcam’s operation and therefore camera from the chrome browser may not work.
Steps to disable the Google flag:
1. Copy and paste chrome://flags/#enable-media-foundation-video-capture on your Chrome browser address bar.
2. Select Disabled from the drop-down list.


3. Relaunch your browser and check if the camera works now.

Not Found Error or Devices Not Found Error

This error occurs when there are no audio/video devices connected or when your computer or microphone does not have a sound card. It can also occur if the recording device is disabled.
If you do not have audio/video devices or a sound card, you can switch to phone audio.

If your hardware does not support certain requirements, this error will be shown.
